oxygen produced by photosensitizer through irradiation. However, the choice of photosensitizer for mosquito control is limited. Here, we report a novel series of naphtho[1,8-ef]isoindole-7,8,10(9H)-trione and oxoisoaporphines derivatives as excellent type II photosensitizers. Meanwhile, the light-dependent activities against permethrin-susceptible and permethrin-resistant strain of Aedes aegypti mosquito
受感染的蚊子是登革热、黄热病、基孔肯雅热、寨卡病毒和其他病原体的重要载体。从增加蚊子幼虫控制的抗性来看,光活化杀虫剂是一种利用光敏剂通过辐照产生的剧毒单线态氧的有前途的方法。然而,用于控制蚊子的光敏剂的选择是有限的。在这里,我们报告了一系列新的萘并[1,8 - ef ] isoindole -7,8,10(9 H )-trione 和oxoisoaporphine 衍生物作为优秀的II 型光敏剂。同时,对埃及伊蚊对氯菊酯敏感和氯菊酯抗性菌株的光依赖活性对这些化合物的蚊子幼虫进行了评估。其中,化合物7b由于其优异的光毒性被证明是潜在的光动力杀虫剂,可见光照射下LC 50值为0.19 μg mL -1。辐射产生的活性增强超过 520 倍。这种化合物可能是寻找新的光活化杀虫剂线索的潜在候选者。重要的是,7b 具有良好的荧光量子产率(φ F = 0.70),可作为蚊子幼虫的荧光指示剂,观察吸收和形态变化。
